 Hello and how are you all today? My name is Priyanka and I shall be helping you with the following question. It says in each of the following exercises one to seven, describe sample space for the indicated experiment. Now here the first experiment given to us is a coin is tossed three times. So we need to describe the sample space when a coin is tossed three times. Now we know that when we toss a coin there is a possibility that we can either get head or tail. Right? So it is a possible outcome that in all the three tosses we will get head or in all the three tosses we will get tail. Right? Then there is a possibility that we will get two times head and one time tail into three manners H, H, T or H, T, H or now again there is a possibility that we will get three two times tail and one time H that is in the first time tail then tail and then head or tail, head, tail or head, tail, tail. So this will be the required sample space and hence the answer will be head, head, head or H, H, T, H, T, H that is head, tail, head then we can have tail, head, head, tail, tail, head or tail, head, tail, tail or head, tail, tail then and then lastly tail, tail, tail. Right? So this is the required sample space for the question that was given to us. Hope you enjoy and understood it well. Have a nice day.
